So I'll ask again. Are you criticizing AGW/Climate Change by saying that it cannot be proven?
I am criticizing the frequent rhetoric where people assume AGW is scientific fact. I am criticizing what I perceive as some "group think" amongst the academic climate change community. I spent the last 7 years in a PhD program and am quite familiar with the "group think" aspects of academia. Circle the wagons and shoot outwards.
What are you driving at when you say you can't prove AGW? That complaint is usually followed by "you can't _scientifically prove_ it therefore we shouldn't do anything about it".
Actually my view is that society should apply some actuary science here (i.e., risk management). GW is happening whether we like it or not, thus a fair amount of money should be spent on researching/improving our ability to adapt. AGW may or may not be happening, and it may be irreversible if it is. Nonetheless, there exists some non-zero probability that AGW is indeed happening and that it is reversible with modest or drastic worldwide action. Thus I absolutely believe we should be purchasing some modest insurance policies (modest meaning 1-3% of global GDPs). What I find unrealistic is calling for such drastic change, given the uncertainties involved, that global economies and balances would rapidly shift.
As an example, I believe the risks of AGW probably outweigh the risks of nuclear power generation (which could *substantially* reduce CO2 emissions).
